I used Liberty's services to replace 2 my AC/heating systems this spring and I am very satisfied with them. Both of my central AC units died in the end of last summer and given the entire systems were 20+ years old I decided to wait the winter and then replace both systems including the furnaces, condensers and coils. In the end of February, I began meeting the local contractors to get estimates for the job, starting with PSE&G certified contractors and then continuing with whoever I could find through references or on internet with more or less positive reviews. During 2-3 weeks I saw and received estimates from about 20-25 of them. Some of them did not impress me, as they said that the work would take 2-3 days for each of my 2 units, others were pricey (I received estimates ranging from 6.5k to 14k per unit), some were striking me as unreliable personalities etc. This is a normal process of picking up the contractor, but it is tiresome and after 2-3 weeks I was ready to compromise with myself and drop some of my "high standards and demands" to just get the job done. Luckily I did not have to do that, since Liberty was one of the last 2 contractors to visit my house and they fit perfectly into every standard of mine and were able to satisfy every expectation I had. The salesperson, Tim, was direct, knowledgeable and provided answers to every question I asked. I was told that the installation of a unit would take 5-6 hours by a crew of 3-4 guys, which was kind of a surprise, since all of the contractors I saw before had a crew of 1-2 guys with estimates of 1 to 3 days for each unit to be replaced. After seeing Tim I continued with Lisa, which was absolute pleasure. She is polite, professional and generally a very nice person to deal with. She never ignored my requests/questions, all the texts that I sent her were answered immediately. All what she/Tim said was proven to be correct down the road - no lies, no misrepresentations, no games or gimmicks. The negotiating process was smooth, we signed the contract very quickly. The price I paid for 2 units was very decent. It was not the cheapest (I received 2 slightly cheaper estimates), but it definitely was a very fair price. The morning after the contract was signed Lisa filed for permits and we scheduled an installation a week after that. Scott/Tyson and 2 other guys arrived in time. They split the work, so 2 guys were replacing the indoor unit, while 2 others were handling the condenser outside. They were super friendly, professional, explained to me whatever I wanted to know about the process/units and worked efficiently and fast. No mess was left behind. In less than 5 hours my attic unit was up and running. The basement unit was replaced in less than 5.5 hours on another day. From my previous experience with contractors, which I had plenty - I was impressed by Liberty's high standards and combination of fair pricing, good quality of work, decency and reliability. It's a rare thing and I definitely recommend Liberty to any homeowner or business for replacing their AC/heating system.
